> because obviously class sizes are limited

Most community college are cancelling classes these days due to low enrollment. They might seat 20, for example, and have 14 in one and only three in another. So they cancel the second section and just move those students into the first if they can. Other times they'll cancel classes altogether.

When I teach adjunct it's about $2,500 for a semester to teach a full load (at least nine students). For every student less than that you get a pay cut, so most adjuncts won't teach for less than a full load. My class this coming spring only has five students, but I said I'd teach it anyway and it's only like $1,400 for approximately 16 weeks of work.
